Description

Technical Field

[0001] This utility model relates to the field of auxiliary fixture technology for display production, and in particular to a magnetic pole detection device for display magnets. Background Technology

[0002] Some monitors have multiple magnets installed on their back covers. In these monitor products, there are installation requirements for the magnetic pole orientation of the magnets on the back cover. Moreover, the magnetic pole orientation of magnets in different positions on the back cover may be different. Therefore, a magnetic pole detection station is needed to detect the magnetic pole orientation of the magnets on the back cover in order to detect the problem of magnets being installed backwards in time. However, at present, there is no magnetic pole detection device in the industry that can detect the magnetic pole orientation of magnets on the back cover. Utility Model Content

[0003] The technical problem solved by this utility model is to provide a display magnet pole detection device, which can detect the orientation of the magnetic poles of the magnets on the back cover of the display.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a display magnet pole detection device, including a machine base and a control board disposed within the machine base. The machine base has a platform, and the platform is provided with multiple limiting blocks. The multiple limiting blocks define a placement position on the platform. The placement position is used to place the back cover of the display to be tested. The bottom of the placement position is provided with multiple magnetic pole orientation detection positions. Each magnetic pole orientation detection position is respectively provided with a magnetic polarity sensor. The machine base is also provided with multiple indicator lights. The indicator lights and the magnetic polarity sensors are electrically connected to the control board. The indicator lights and the magnetic polarity sensors correspond one-to-one.

[0005] In one embodiment, the magnet polarity sensor is a Hall sensor.

[0006] In one embodiment, a buzzer is also provided on the machine base, and the buzzer is electrically connected to the control board.

[0007] In one embodiment, a relay is also included, through which the control board is electrically connected to the buzzer.

[0008] In one embodiment, the indicator light is a dual-color LED.

[0009] In one embodiment, the platform is further provided with a pick-and-place slot, which includes a first area and a second area that are connected to each other. The first area is located on one side of the second area, the first area is in the placement position, and the second area is outside the placement position.

[0010] In one embodiment, the second region is connected to the peripheral wall of the platform.

[0011] In one embodiment, the platform is provided with a clearance hole, which is located in the placement position.

[0012] In one embodiment, handles are provided on opposite sides of the machine.

[0013] In one embodiment, the bottom of the machine is provided with foot pads.

[0014] The beneficial effects of this utility model are as follows: This display magnet pole detection device has a simple and novel structure. The magnet with reversed poles on the back cover can be detected by the magnet polarity sensor. When the magnet polarity sensor detects that the magnet pole orientation is incorrect, it will send a signal to the control board. The control board will control the corresponding indicator light to emit a light reminder, so that the tester can quickly identify the magnet with reversed poles so that rework can be carried out. This greatly improves the detection efficiency of magnet pole orientation detection. Moreover, during the detection process, the tester only needs to pick up and put down the back cover of the display on the table. The whole operation process is time-saving and labor-saving, which helps to reduce the cost of magnetic pole orientation detection. Attached Figure Description

[0031] Example 1

[0032] Please refer to Figure 1 and Figure 2The first embodiment of this utility model is: a display magnet pole detection device, used to detect whether the orientation of the magnetic poles (N pole and S pole) of each magnet 61 on the back shell 6 of the display is incorrect.

[0033] The display magnet pole detection device includes a machine base 1 and a control board (not shown in the figure) disposed within the machine base 1. The control board is a PCB board, on which a control circuit and a microcontroller unit (MCU) electrically connected to the control circuit are provided. The machine base 1 has a platform 11, on which a plurality of limiting blocks 12 are provided. The plurality of limiting blocks 12 define a placement position 13 on the platform 11. The placement position 13 is used to place the back cover 6 of the display to be tested. When the back cover 6 is placed on the machine base 1, the limiting blocks 12 limit the position of the back cover 6, thereby allowing the back cover 6 to be accurately placed in the placement position 13. Specifically, the placement position 13 is rectangular, and its position is defined by the back cover 6. The shape and contour are adapted; the bottom of the placement position 13 is provided with multiple magnetic pole orientation detection positions 14, and each magnetic pole orientation detection position 14 is respectively provided with a magnetic polarity sensor 2. Optionally, the magnetic polarity sensor 2 is a Hall sensor that can detect the magnetic pole orientation; the machine base 1 is also provided with multiple indicator lights 3. The indicator lights 3 and the magnetic polarity sensors 2 are electrically connected to the control board. The indicator lights 3 and the magnetic polarity sensors 2 correspond one-to-one. After the back cover 6 is placed in the placement position 13, when the magnetic pole orientation of a certain magnet 61 is reversed, the corresponding indicator light 3 will emit a light reminder, while the indicator lights 3 corresponding to the magnets 61 that have not been reversed will not emit a preset light reminder.

[0034] In this embodiment, the indicator light 3 is a dual-color LED light, which can emit both red and green light. After the display magnet pole detection device is started, each indicator light 3 will be constantly lit and emit green light. During the detection process, when the magnetic pole of a magnet 61 on the back cover 6 is reversed, the corresponding indicator light 3 will emit red light.

[0035] To enable inspectors to better detect the reversed pole installation of magnet 61, the display magnet pole detection device of this embodiment is equipped with a dual warning mechanism. Specifically, the display magnet pole detection device also includes a buzzer 4 mounted on the machine base 1, which is electrically connected to the control board. More specifically, the display magnet pole detection device also includes a relay (not shown in the figure), which is electrically connected to the buzzer 4 via the relay, and the relay is mounted on the control board.

[0036] To facilitate the handling of the back cover 6 by testing personnel and further improve testing efficiency, the platform 11 is also provided with a handling slot 15. The handling slot 15 includes a first area and a second area that are connected. The first area is located on one side of the second area and is situated in the placement position 13, while the second area is located outside the placement position 13. Preferably, the second area is connected to the peripheral wall of the platform 11, which facilitates the processing and shaping of the handling slot 15 and reduces the probability of the testing personnel's hands being bumped or scratched.

[0037] The platform 11 is provided with a clearance hole 16, which is located in the placement position 13. The clearance hole 16 can avoid the protruding structure on the rear shell 6.

[0038] Optionally, the machine base 1 is provided with handle positions 17 on opposite sides. The presence of handle positions 17 facilitates the inspection personnel to move and transfer the display magnet pole detection device. In this embodiment, the handle positions 17 are through slot structures.

[0039] The bottom of the machine base 1 is equipped with foot pads 5.

[0040] The above are merely optional embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
